don´t know if you call it a bug, perhaps it is wanted this way, but when i export a scene set up in cinema 4d, every object has its own material in studio. even if i had 20 times the same material in cinema 4d.

would be better, if only one material was created and applied to all objects having this one applied.

so the material list in studio would be way cleaner.

and, you should be able to select multiple materials in order to delete them from the material list.
